Did you miss the part about training more? It's pretty much the whole summary.
There is a very odd misconception in the world today. That is the idea, that all you have to do is plug in someone, anyone, into a job slot, and the results are the same.
It certainly isn't. The question that needs asked, is do an equal amount of young women even want to become programmers?
I have participated in many "Take your sons and daughters to work" days, and have been in on the efforts to get young women interested in tech fields and engineering.
These are the daughters of tech people and engineers, so you would expect there to be some interest.
Haven't found much at all. The young ladies prefer fields like lawyers, MBA's, and medical fields. This is a sampling of hundreds.
So we are left with perhaps forcing young ladies into tech fields?
